Birkerod,丹麦， 2010年1月25日—NKT Photonics A/S (NKT光子)公司宣布推出新一代的CRYSTAL FIBRE系列双包层棒状光子<a href="http://material.oecr.com" target="_blank" class="relatedlink">晶体</a>光纤，型号为DC-285/100-PM-Yb-ROD，该光纤基于CRYSTAL FIBRE专利的空气包层（Air-clad）技术，该光纤的特点包括：严格单模，达到100um直径的偏振保持（PM）型纤芯，高泵浦吸收，和低光子暗化效应（Photodarkening），这种掺镱的棒状光子晶体光纤的典型应用是高功率脉冲<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>放大多级系统的输出级，能够承受兆瓦级（Mega-Watt）峰值功率输出水平。<br /> <br /> 多年以来，光纤业界转向CRYSTAL FIBRE寻求高性能光纤放大器的最领先的解决方案，今天，NKT Photonics推出CRYSTAL FIBRE棒状双包层掺镱光子晶体光纤满足兆瓦（MW）峰值功率的光纤放大器应用需求。DC-285/100-PM-Yb-ROD是一款偏振保持型光纤，纤芯模场直径76um的掺镱纤芯能够得到超过4500um2的有效模场面积，285um直径的泵浦纤芯能够接受数值孔径可达0.55的915nm或者976nm泵浦，采用976nm泵浦时，吸收达到30dB/m.<br /> <br /> DC-285/100-PM-Yb-ROD棒状光子晶体光纤能够得到稳定的（Robust）单横模光束质量的输出，该光纤经过了平均功率超过100W，不同脉冲宽度和重复频率条件下的<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测试</a>。<br /> <br /> DC-285/100-PM-Yb-ROD棒状光子晶体光纤为工业级客户的OEM应用而设计，可以用来进一步提升现有的光纤放大器输出能量水平，或者替代传统的晶体“棒”，例如Nd:YAG, Nd:YVO4, Nd:YLF等等。和传统的激光晶体棒相比，棒状光子晶体光纤能够提供高光束质量的信号和泵浦波导，没有热透镜效应。DC-285/100-PM-Yb-ROD棒状光子晶体光纤具有高的信号单通增益，偏振消光比（PER）超过15dB，泵浦吸收和偏振态无关。<br /> <br /> DC-285/100-PM-Yb-ROD棒状光子晶体光纤现在可以直接供货，库存的标准规格<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>包括端面密封（End-sealed）和带角度切割（Angle cleaved），或者8x8mm镀增透膜（AR coated）的石英光纤端帽（End-caps）等。<br /> <br /> 关于DC-285/100-PM-Yb-ROD棒状光子晶体光纤更多的详细信息请注意浏览公司网站<a href="http://www.shconnet.com.cn" target="_blank">www.shconnet.com.cn</a>或者联系我们的服务人员。 <br /> <br /> 关于NKT Photonics A/S<br /> NKT Photonics A/S设计生产商用级和工业级特种微结构光纤和高功率光纤放大器。公司同时设计制造光纤基础的工业级系统例如白光激光器和超精密的DFB光纤激光器。这些系统已经在包括生物光子学，计量，光纤<a href="http://sensor.oecr.com" target="_blank" class="relatedlink">传感</a>器，相干<a href="http://ofc.oecr.com" target="_blank" class="relatedlink">通信</a>，测试<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测量</a>，高精度光谱学以及激光雷达等众多市场领域得到了商业化的应用。NKT Photonics A/S属于丹麦工业巨擘NKT Holding A/S (NKT控股公司)全资拥有。<br /> 需要了解关于NKT Photonics A/S公司更多的信息，请浏览该公司网站： <a href="http://www.nktphotonics.com" target="_blank">www.nktphotonics.com</a><br /> <br /> 关于上海瀚宇<br /> 上海瀚宇此前是Koheras A/S公司以及Crystal
